Fortnite’s newest patch, v6.20, is the biggest of the year so far, and not just because of the Halloween event. While Fortnitemares is likely going to be what holds most players’ attention, this patch also includes a few more additions to the game.

First, v6.20 will return the revolver from the vault, while also updating the gun to give it a more defined place in the game. Meanwhile, Epic is also adding some new items to Playground mode and testing out some changes that would allow players to redeploy their glider during any Battle Royale game.
